The bench press or chest press is a weight training exercise where a person presses a weight upwards while lying horizontally on a weight training bench. The bench press is a compound movement, with the primary muscles involved being the pectoralis major, the anterior deltoids, and the triceps brachii. Other muscles located in the back, legs and core are involved for stabilization. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used. [1]
The barbell bench press is one of three lifts in the sport of powerlifting alongside the deadlift and the squat, and is the only lift in Paralympic powerlifting. The bench press is also extensively used in weight training, bodybuilding, and other types of training to develop upper body muscles, primarily the pectoralis major. To improve upper body strength, power, and endurance for athletic, occupational, and functional performance as well as muscle development, the barbell bench press is frequently used. [2]

The person performing the exercise lies on their back on a flat bench with a barbell grasped in both hands. They lower the barbell to chest level until it touches the chest, then press the barbell upwards, extending the arms until the elbows are locked out. This is one repetition (rep).
The bench press has evolved over the years, from floor, bridge, and belly toss variations to the methods used by bodybuilders and powerlifters today. It became popular from the late 1950s onwards. [3] Despite the fact the parallel dip is safer (the dip does not require spotters or safety bars [3] ), in the 1950s the bench press took over the dip in popularity and became the standard fare for chest exercises. [3]
At first the strict floor press was the most popular method. In 1899, using a barbell with 48 centimetres (19 in) discs (plates), George Hackenschmidt, inventor of the barbell hack squat, rolled a barbell over his face (which was turned to the side) and performed a strict floor press with 164 kilograms (362 lb). This stood as a record for 18 years until Joe Nordquest broke it by 1 kilogram (2.2 lb) in 1916.
Around this time, new methods started gaining ground. Lifters began to discover that strong glutes could help them get the bar from the ground to overhead. They would lie on the floor and position the bar over their abdomen, then perform an explosive glute bridge movement, catapulting the bar upwards and catching it at lockout. [4]
Lifting techniques, training, and drugs have improved over the years and the bench press record lift has grown from 164 kilograms (362 lb) to 355 kilograms (783 lb) (raw, record held by Julius Maddox) in approximately 100 years. [5]

A conventional bench press uses the pectoralis major, front deltoids, [6] and triceps brachii to horizontally adduct the shoulder. While flat bench pressing, the pectoralis major and pectoralis minor muscles are activated. [7] [8] The exercise also uses the triceps and anconeus to extend the elbows. [6] The triceps are most crucial around the end of the press to help complete and lock out the elbows. With the right form, parts of the deltoids will be used to help make the lift, including the anterior deltoids. [6] Wider hand spacing places a greater emphasis on shoulder flexion and narrower hand spacing utilizes more elbow extension. Because of this, wider hand spacing is associated with training the pectorals and narrower hand spacing is associated with training the triceps. Both close and wide hand spacing trains the deltoid area. [6]
In addition to the major phasic (dynamic) muscles, the bench press also uses tonic (stabilizing) muscles, including the scapular stabilizers (serratus anterior, middle, and inferior trapezius), humeral head stabilizers (rotator cuff muscles), and core (transverse abdominis, obliques, multifidus, erector spinae, quadratus lumborum.)

Variations of the bench press involve different groups of muscles, or involve the same muscles in different ways:
Performing the bench press can contribute to multiple types of injuries:
Many of these possible injuries can be avoided by using dumbbells instead of a barbell since dumbbells can be dropped without hitting the chest or neck, while also allowing greater external rotation of the shoulder which can help prevent shoulder injuries. Studies have also shown dumbbell bench press activates the pectorals more, which can lead to increased muscle growth. [20]
The push-up is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, and some martial arts disciplines to humiliate and its absence of use for equipment. Variations of push-ups, such as wide-arm push-ups, diamond push-ups target specific muscle groups and provide further challenges.
Bicep curls are a group of weight training exercises in which a person bends their arm towards their body at the elbow in order to make their biceps stronger.
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help the hip muscles.
The deadlift is a weight and strength training exercise in which a loaded barbell is lifted off the ground to the level of the hips, with the torso perpendicular to the floor, before being placed back on the ground. It is one of the three powerlifting exercises, along with the squat and bench press, as well as a frequent lift in strongman. It is also occasionally used in armlifting. The deadlift is widely considered the King of all exercises.
The snatch is the first of two lifts contested in the sport of weightlifting followed by the clean and jerk. The objective of the snatch is to lift the barbell from the ground to overhead in one continuous motion. There are four main styles of snatch used: snatch, split snatch, power snatch, and muscle snatch. The full lift is the most common style used in competition, while power snatches and muscle snatches are mostly used for training purposes, and split snatches are now rarely used. Any of these lifts can be performed from the floor, from the hang position, or from blocks. In competition, only lifts from the floor are allowed.
In weight training, the shoulder shrug is an exercise used to develop the upper trapezius muscle.
The lying triceps extension, also known as skull crusher and French extension or French press, is a strength exercise used in many different forms of strength training. It is one of the most stimulating exercises to the entire triceps muscle group in the upper arm, and works the triceps from the elbow all the way to the latissimus dorsi. Due to its full use of the triceps muscle group, the lying triceps extensions are used by many as part of their training regimen.
In weight training, a kettlebell is a cast-iron or cast-steel ball with a handle attached to the top, resembling a cannonball with a handle. It is used to perform many types of exercises, including ballistic exercises that combine cardiovascular, strength and flexibility training. Kettlebells are the primary equipment used in the weight-lifting sport of kettlebell lifting.
A bent-over row is a weight training exercise that targets a variety of back muscles depending on the form used. It is often used for both bodybuilding and powerlifting.
The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
The following outline is provided as an overview of and topical guide to exercise:
The upright row is a weight training exercise performed by holding a weight with an overhand grip and lifting it straight up to the collarbone. This is a compound exercise that involves the trapezius, the deltoids and the biceps. The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
The overhead press, also known as the shoulder press, strict press or military press, is an upper-body weight training exercise in which the trainee presses a weight overhead while seated or standing. It is mainly used to develop the anterior deltoid muscles of the shoulder. The standing version was once a component of the sport of Olympic weightlifting as part of the clean and press movement, but was removed in 1972 due to difficulties in judging proper technique.
A fly or flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle. Flies are used to work the muscles of the upper body. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles . Due to this leverage, fly exercises of all types have a large potential to damage the shoulder joint and its associated ligaments and the tendons of the muscles connecting to it. They should be done with caution and their effects first tested while using very light weights; which are gradually incremented after more strength is gained.
A dip is an upper-body strength exercise. Close grip dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. Wide shoulder width dips place additional emphasis on the pectoral muscles, similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the triceps.
The front raise exercise is used in weight training. It primarily works the anterior deltoid and the clavicular head of the pectoralis major through the use of arm abduction and flexion through the frontal plane. The training volume, or number of sets and repetitions performed, depends on the lifter's training program and goals.
The rear delt raise, also known as the rear deltoid raise, or rear shoulder raise is an exercise in weight training. This exercise is an isolation exercise that heavily works the posterior deltoid muscle. The movement is primarily limited to the two shoulder joints: the glenohumeral joint and the scapulothoracic joint. Scapular movement will also cause movement in the sternoclavicular joint and acromioclavicular joint. If the elbow bends during the extension exercises, it gravitates into a rowing motion.
A machine fly, alternatively called a seated lever fly or "pec deck" fly is a strength training exercise based on the free weight chest fly. As with the chest fly, the hand and arm move through an arc while the elbow is kept at a constant angle. Flyes are used to work the muscles of the upper body, primarily the sternal head of the pectoralis major. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles. Denie Walter is credited with calling it the Peck Dec back in the 1970s.
The pullover is an exercise that is performed with either a dumbbell or a barbell. Pullovers can be made to affect either the chest or the back depending on how wide the grip is (barbell) and the position of the shoulders. A research done on the pullover movement using a barbell suggested more effect on the pectoralis major muscle as compared to the latissimus dorsi.
